Notes

When ordering, please specify termination code: e.g. RFS1113-275ME
Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc; measured on an Agilent/HP 4284A LCR-meter or equivalent.
DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
SRF measured using an Agilent/HP 4191A or equivalent. Details
Isat: DC current at 25°C that causes the specified inductance drop from its value without current. Temperature derating curves.
Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.

Termination:

E = RoHS compliant tin-silver (96.5/3.5) over tin over copper over steel.
T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
S = non-RoHS tin-lead (63/37). (Special order, added cost)
